Open source codes for turbulent flows

A curated list of some open source frameworks, libraries and softwares for turbulent flow simulations. This list includes solvers for turbulent multiphase, turbulent reacting flows, turbulent convection and turbulent atmospheric physics as well. This list is by no means complete. So if you would like me to add something, please send me a link to [email protected] or perform a pull request.

Numerical frameworks (physics-based)

  • AFiD [1] - an MPI parallelized numerical solver for DNS of turbulent Rayleigh-Benard and Taylor-Couette flows. Employs pencil distributed finite differences. Developed at the Physics of Fluids group, University of Twente and Universita di Roma Tor Vergata.
  • AFiD-GPU [2] - GPU version of the AFiD code mentioned in the above point.

  • HAMeRS - Hydrodynamics Adaptive Mesh Refinement Simulator. An MPI parallellelized C++ numerical solver for the compressible NSE with patch-based adaptive mesh refinement (AMR). Utilizes high-order conservative shock and interface capturing Weighted Compact Nonlinear Schemes (WCNS). Developed by the Flow Physics and Aerocoustics laboratory, Department of Aeronautics and Astronautics at Stanford University.

Includes capabilities for wind turbine modeling, level set immersed boundary methods and atmospheric boundary layer flows as well. Developed at the Turbulence research group at John Hopkins University.
  • NALU [8] - a parallelized numerical framework for unstructured meshes which uses control volume finite element (CVFEM) and edge-based vertex centered (EBVC) discretization approaches. Supports LES, RANS and DES turbulence models. Developed at the Sandia National laboratories.
  • Nek5000 [9] - a massively parallelized MPI numerical solver for simulating turbulent incompressible flows (uses low Mach NSE equations). Employs higher-order spectral methods.
